SNOW-S CRAPER.

SPECIFICATION forming part of Letters Patent No. 418,327, dated December 31, 1889..

Application filed October 25, 1889.

T0 all wim/m t may concern:

Be it known that I, ORLIN S. VHEELER, a citizen of the United States, residing at Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Suow-Scrapers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates, generally, to snowscrapers having an adjustable scraping or face board suitably mounted upon runners and adapted to scrape up an d remove the snow from the surface of an ice-field preparatory to harvesting.

The objects of my invention are, first, to securely fasten the face-board in an inclined position when inthe act of scraping; second, to cause the face-board to bereadily changed from an inclined to a substantially-horizontal posit-ion, so as to serve as means for carrying the accumulated snow off to the du1np-I ing-place, and, third, to provide means for overturning the face-board and dumping its load, when desired. These objects I accomplish by substantially the devices illustrated in the accompanying drawings, in which- Figure l represents aside view of a scraper embodying my invention, showing in full lines the position and arrangement of the parts when the face-board is inclined in the act of scraping, and showing in dotted lines the face-board in substantially a horizontal position. Fig. 2 represents aplan View of the parts shown in Fig. 1. Fig. 3 represents a side view of the scraper shown in Figs. land 2, the several parts being' arranged in the position assumed by them after the face-board has been overturned. Fig. ll: representsa detached view of a swinging hanger; Figx, an enlarged side view of a bracket prov1 ded with a locking projection and a series of holes.

A represents runners, which may be of any suitable construction, connected, together at their forward ends by means of the cross-bar fn. Attached to the cross-bar is a pole, to which the team is connected. The rearends of -the runners are connected together by means of the bent hanger G, having its ends f offset, so as to form trunnions, which are serai No. 328,188.A (No model.)

'journaled in the rear ends of the runners A, thereby allowing a Vbackward and forward 4independently-swinging movement of the ihanger. A face-board B is supported bythe hanger G, and is secured thereto by means of loops t overlapping the hanger and attached lto the under side of the face-board. Instead lof the loops t, ordinary bearing-boxes may be used or other means of suitable construction iwhich will allow free rocking movement of ythe faceboard on the hanger independently 'of any similar movement of the hanger itself. 'Attached to the face-board are sides B and backboard B2, forming with the face-board a shovel or other receptacle for holding a quantity of snow. A knife or metallic scraper- `blade O is secured to the forward edge of the face-board.

Pivotally attached to the face-board at a point about on the line of the hanger is a lever F. The forward end ofthe lever is provided with a notch K, which engages with a projection K', formed on the bracket O, attached to tl1ecross-bar, by means of which projection and the engaging-notch K the forward end of the lever Fis detachably secured to the cross-bar. forward end to the cross-bar and projects at its rear end beyond the back edge of the faceboard. The free end of this lever is provided with a projection c, which is adapted to engage with the edge of the back board B2 or the rear edge of the face-board and hold the face-board in an inclined or scraping position. An auxiliary leverE is pivotally secured to the back board and is providedat its forward end with alongitudinal slot a which engages'with a pin a', attached to the lever D. The forward end of the auxiliary lever E, when in the position` shown in Fig. l, presses `against the pin a', attached to thelever D, and in effect forms with that portion of the lever D extending from the point a to the point d one continuous brace, adapted to resist any forward pressure exerted by the back edge of the faceboard, while the slot ct permits a change of the relative position of these parts to adapt the face-board to be thrown forward into the position shown in Fig. 3, when desired. A stirrup or hanger m is pivoted at its upper end to the bar D by means of a pin Z,and has a limited swinging movement forward and A lever D is pivoted at its IOO backward on said pivot. To the lower end of the stirrup awheel m is pivotally secured, which avoids frictional movement when the lower end of the stirrup comes in contact with and moves along the lower edge of the lever F. i

I do not desire to be limited to the specific construction of the vstirrup shown herein, but desire to include any other means having similar capabilities. The object and purpose of said stirrup is to connect the upper lever D with the lower lever F in such a manner that when the free endof the lever D is raised it will draw -up with it the forward end of the lever F and release the notch K from the projection K.

Attached to the cross-bar n is a bracket C, provided with a series of holes d', by means ofwhich the position of the lever D is regulated, so as to adjust the face-board at the desired inclination, and thereby regulate the depth of cut. These holes are arranged at points varying in distance from the rear end 0f the face-board, and when the forward end of the lever D is connected to the bracket C by means of a pin engaging with the brackethole nearest to the shaft the catch e on the rear end of the lever will be in engagement with the rear end of the face-board or with the back board, as shown in Fig. l, the faceboard will be inclined to its fullest capacity, and its forward or cutting edge will be in direct contact with the surface ofthe ice. l/Vhen it is desired to diminish the depth of cut, the pin d is removed and inserted in one of the bracket-holes farther back, so as to move the lever D slightly backward. By pressing down on the handle g of the lever the back edge of the face-board will be pressed slightly downward until it comes in contact with the projection e, and the forward edge of the face- -board will then be raised slightly off the ice,

When a sufficient quantity of snow has been scraped together and it is desired to remove it from the iield, the lever D is lifted upward by means of the handle g, releasing the projection e from engagement with the back edge of the face-board. When the lever D is thus raised, the forward end of the lever F is also raised by means of the connectingstirrup m and the notch K released from the catch K. The face-board will then be free to assume a substantially-horizontal position, as indicated by the dotted lines in Fig. l, and in this position the mass of snow may be removed to any desired place. Vhen the dumpingplace has been reached and it is desired to deposit the snow, the back end of the face-board is lifted up by means of the handle h, the forward edge of the face-board catches into the ice and the adhering coating ofsnow, and is overturned by a continuation of the forward movement of the machine7 as indicated in Fig. 3. The faceboard may be readily drawn back into working position by means of the handle h.

The devices herein shown for holding the face-board securely in position and for overturning the same may be used, if desired, with other means than the bent swinging hanger G shown herein for mounting the face-board upon runners wit-hout departing from my invention, and some of the devices may be used without the others.

I do not claim herein the swinging hanger for supporting the face-board, nor the runners land connecting cross-bar having draft mechanism attached thereto, as such subjectmatter is claimed by me in another application tiled February 20, 1889, Serial No. $00,594:.

What I claim is 4 l. In a snow-scraper,the combination,with a face-board suitably mounted upon runners,

`of the locking-lever F, pivoted to the faceboard, the lever D, pivoted to the cross-bar, auxiliary lever E, and means for connecting the levers D and F together, substantially as shown and described.

2. In a snow-scraper, the combination, with a face-board suitably mounted upon runners, of the lever D, pivoted to the cross-bar, and auxiliary lever E, provided with a longitudinal slot engaging with a pin secured to the lever D, the locking-lever F, pivoted to the face-board and adapted to engage with the cross-bar, and the stirrup m, pivoted to the lever D and provided with a wheel pivotally supported by the lower end of said stirrup, substantially as shown and described.

3. In a snow-scraper, the combination, with a face-board suitably mounted upon runners, of the lever D, provided with the locking projection e, and the auxiliary lever E, provided with a longitudinal slot engaging with a pin attached to the lever D, substantially as shown and described.

4. In a snow-scraper, the combination, with suitable runners connected together by a cross-bar, of a face-board mounted upon said runners and movable bodily backward and forward independently thereof, a lever F, pivoted tothe face-board, lever D, pivoted to the cross-bar, auxiliary lever E, adj ustably connected with the lever D, the stirrup m, and perforated bracket C, substantially as shown and described.

In testimony whereof I afiix my signature in presence of two witnesses.
